Hybrid tea rose plant named ‘JACepirt’

ABSTRACT

Hybrid tea rose plant having large, bright pink and light yellow striped flowers having a spicy fragrance; dark green, glossy foliage and vigorous, upright growth.

BOTANICAL CLASSIFICATION

Rosa hybrida ‘JACepirt’.

The present invention relates to a new and distinct variety of rose plant of the hybrid tea class which was originated by me by crossing an unnamed seedling with an unnamed seedling.

The primary objective of this breeding was to produce a new rose variety having the bright pink and white stripes on the flowers of the hybrid tea female parent combined with the vigorous growth, large flower size and fragrance of the male parent. The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Bright pink and light yellow striped flowers;

2. Large flower size;

3. Vigorous, upright growth;

4. Spicy fragrance; and

5. Dark green, glossy foliage.

Asexual reproduction of this new variety by budding on Dr. Huey understock, as performed at Wasco, Calif., shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetative growth and flowers of this new variety in different stages of development, depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar with color descriptions using terminology in accordance with The Royal Horticultural Society (London) Colour Chart (1966), except where ordinary dictionary significance of color is indicated.

Parentage:

Seed parent.—Unnamed. (unnamed seedling×unnamed seedling.).

Color.—The upper sides of the petals are Red Group 53D on the outer portions with areas of Yellow Group 8D. The inner third of the petal is Yellow Group 8C. The reverse sides of the petals are Yellow Group 8C except around the petal edge where there is a thin line of Red Group 53D. The base of each petal has a small ({fraction (3/16)}″×{fraction (3/16)}″) area of Yellow Group 13B on the upper surface. The lower surface has no discernible color spot. The major color on the upper side is Red Group 53D.

Reproductive parts:

Stamens.—Number: 180-200. Anthers: Length: {fraction (1/16)} inch. Color: Yellow-Orange Group 16C. Arrangement: Regular around styles. Filaments: Color: Yellow-Orange Group 16C, but near the base become Yellow-Orange Group 17D. Length: {fraction (3/16)} inch. Stigmas: Pollen: Color: Yellow-Orange Group 22B.
